TECHNICAL FIELD

The present disclosure relates to a cutting structure and a sewing process for back wearing protective clothing, and belongs to the technical field of clothing.

BACKGROUND

Novel coronavirus (2019-nCoV) has brought great changes to people's lives in 2019. Because the main transmission routes of novel coronavirus are respiratory droplet transmission and contact transmission, medical materials, such as respirators and protective clothing, are in short supply

The existing medical protective clothing is treated in the treatment manners of opening in front, adding a zipper at an opening structure, or the like, and is added with windshield for protecting. Because medical staff need to be in contact with patients in front frequently in the process of work, although seams are spliced by pressing medical adhesive strips for protection and adding windshield for protection in the prior art, there is still a high risk that the virus harms the medical staff through a front opening. The existing protective clothing is opened in front, so the medical staff cannot perform backhand operation, and cannot roll the protective clothing from top to bottom while taking off it. A polluted surface of the protective clothing cannot be rolled in a taking off process, so secondary pollution is easily produced, and the safety is poor.

The back waist seam 13 is formed between the upper right sleeve seam 9 and the lower right sleeve seam 10. The upper middle waist seam 14 is formed between the lower right sleeve seam 10 and the lower left sleeve seam 12. The lower neck interface 15 is formed in the middle area of the upper section cutting piece 2. The upper section opening 16 is formed between the lower neck interface 15 and the back waist seam 13. The lower middle waist seam 17 is formed in the top end of the trouser cutting piece 3. The front crotch seam 18 is formed in one side of the upper part of the trouser cutting piece 3. The back crotch seam 19 is formed in the other side of the upper part of the trouser cutting piece 3. The back trouser seam 20 is formed in one side of the lower part of the trouser cutting piece 3. The front trouser seam 21 is formed in the other side of the lower part of the trouser cutting piece 3. The trouser openings 22 are reserved above the back crotch seams 19. In the sewing process of the protective clothing by using the cutting structure described above of the present disclosure, the following steps are performed in sequence: sewing the cap cutting piece 1: overlapping and stitching the cap top seams 7 that are in left-right symmetry on the cap cutting piece 1, and stitching to the positions of the cap openings 8 to form the cap structure with the eye gap 4; sewing the upper section cutting piece 2: sewing the upper right sleeve seam 9 and the lower right sleeve seam 10 of the upper section cutting piece 2 to form the right sleeve; sewing the upper left sleeve seam 11 and the lower left sleeve seam 12 of the upper section cutting piece 2 to form the left sleeve; sewing the trouser legs: sewing the right front trouser seam 21 and the back trouser seam 20 of the trouser cutting pieces 3 to form the right trouser leg; sewing the left front trouser seam 21 and the back trouser seam 20 of the trouser cutting pieces 3 to form the left trouser leg; sewing the crotch: aligning the left and right trouser cutting pieces 3, sewing the front crotch seams 18 of the left and right trouser cutting pieces 3, and sewing the back crotch seams 19 of the left and right trouser cutting pieces 3 to form the crotch seam position of ready-to-wear clothing; sewing the waist seams: sewing the upper middle waist seam 14 of the upper section cutting piece 2 and the lower middle waist seams 17 of the trouser cutting pieces 3, and sewing the back waist seam 13 of the upper section cutting piece 2 and the lower middle waist seams 17 of the trouser cutting pieces 3, so that a main body is formed after sewing; connecting the cap and the main body: resewing the sewn cap cutting piece 1 and the lower neck interface 15 of the sewn upper section cutting piece 2 through the upper neck interface 6. By the sewing process, the opening of the made protective clothing is located at the back. After medical staff wear the protective clothing, the back is opened, only the position of an eyeshade is reserved, and the clothing body, the nose, and the mouth are all within the scope of protection, which greatly reduces the risk that virus enters through the opening to harm the medical staff, and improves a protection effect on the medical staff. A back wear type is adopted, so the medical staff can roll the protective clothing from top to bottom while taking off it. A polluted surface (namely, the front surface) of the protective clothing can be directly rolled in a taking off process and is placed into a medical waste bag. The taking off process is more convenient than that of conventional protective clothing. Secondary pollution is not produced in the whole process, so the use safety of the protective clothing is greatly improved.
